Kuumbwa Kwemakemikari
Q275 simbi ndiro imhando yekabhoni structural simbi, kusimba kwepamusoro, kunaka kwepurasitiki uye kucheka kuita, kuita kwakanaka welding, zvidimbu zvidiki zvinogona kudzimwa nekusimbiswa, zvakanyanya kushandiswa kugadzira zvikamu zvine zvakakwirira zvinodiwa, senge magiya nemashaft. , sprockets, makiyi, mabhaudhi, nzungu, simbi dzechikamu chemichina yekurima, cheni dzekutakura uye zvinongedzo.
Q275 simbi ndiro yakaenzana zvinhu: inoenderana neJapan JIS brand: SS490
International Organisation for Standardization:
E275A
Inoenderana neiyo yekare brand: A5
Kemikari inoumbwa (chikamu chehukuru) cheQ275 simbi ndiro (%)
C: ≤0.24

Si: ≤0.35
S: ≤0.050 (Kirasi A)
P: ≤0.045
Q275 simbi ndiro inonyanya kushandiswa kugadzira akakosha emuchina zvikamu mukuvaka uye bhiriji engineering, uye inogona kutsiva yepamusoro-mhando kabhoni simbi. Q215B yakaenzana neNhamba 10-15. Q235B yakaenzana ne15-20 simbi, Q255B yakaenzana ne25-30 simbi, uye Q275B yakaenzana. 35-40 simbi.
